Viscount Waverley: My Lords, negotiating a broad network of water PPP awards similar to that which has worked well in Gaza could be a strategy. However, I draw attention to the use of the term “sub-Sahara”, which many consider to have overtones from a bygone colonialist and racist area and so to have had its day. Would it therefore not be better to exercise our minds on Africa geostrategically, to include north Africa and the Maghreb?
